There is nothing wrong with chucking money at Archive to help with costs, provided that money does not come with menaces. The basic idea is that if you profit in some way from an open repository of ... something then why not contribute to it? If enough people/orgs contribute then we are all good. Otherwise, if the org behind the project is an individual doing it as a hobby and they can't afford to continue then they might need support.
In the end Archive and co have costs attached. You don't have to contribute but it might be nice if you did.
